How to Adjust a Hunter PGP Sprinkler Head

The Hunter PGP sprinkler head can be adjusted by anyone. You do not need to call the installer if you need to change the arc or the throw radius. Each of these will need adjustment, depending on how much ground you want the sprinklers to cover. If you install new sprinklers -- or add different ways of watering your lawn -- you may need to adjust your Hunter sprinklers.
